Have you had a good look at Factor? FWIW I've got at least the first 3 days with it up here.

Some more Factor solutions for the first 3 days (so far) from soweli Niko, on Codeberg.

Factor

A lot of Forth discussion in the HN comments:

Sure, but nox is the closer counterpart for in-venv-task definitions. List "sessions" with -l, pick specific sessions to run with -s.

import nox
from nox.sessions import Session

nox.options.reuse_existing_virtualenvs = True
APP_NAME = 'logging_strict'

@nox.session(python='3.12')
def mypy(session: Session):
    """Static type checker (in strict mode)"""
    session.install('-U', 'mypy', '.')
    session.run('mypy',  '-p', APP_NAME, *session.posargs)

Unfortunately it doesn't currently do any parallel runs, but if anyone wants to track/encourage/contribute in that regard, see nox#544.

As someone's new comments just brought me back to this post, I'll point out that these days there's another good option: uv run.

No, I don't use GHA locally, but the actions are defined to run the same things that I do run locally (e.g. invoke nox). I try to keep the GHA-exclusive boilerplate to a minimum. Steps can be like:

- name: fetch code
  uses: actions/checkout@v4

- uses: actions/setup-python@v5
  with:
    allow-prereleases: true
    python-version: |
      3.13
      3.12
      3.11
      3.10
      3.9
      3.8
      3.7

- run: pipx install nox

- name: run ward tests in nox environment
  run: nox -s test test_without_toml combine_coverage --force-color
  env:
    PYTHONIOENCODING: utf-8

- name: upload coverage data
  uses: codecov/codecov-action@v4
  with:
    files: ./coverage.json
    token: ${{ secrets.CODECOV_TOKEN }}

Sometimes if I want a higher level interface to tasks that run nox or other things locally, I use taskipy to define them in my pyproject.toml, like:

[tool.taskipy.tasks]
fmt = "nox -s fmt"
lock = "nox -s lock"
test = "nox -s test test_without_toml typecheck -p 3.12"
docs = "nox -s render_readme render_api_docs"
